I discovered a work-around, suggesting a bug. While sound was working correctly (6.9.x kernels) I had a modprobe option: >> options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin however that parameter was refactored out of the snd-sof-intel-hda-common module.
The quirk list sound/pci/hda/patch_realtek.c ~ line 10847 contains: >> SND_PCI_QUIRK(0x17aa, 0x3801, "Lenovo Yoga9 14IAP7", >> ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN), however the sub-ident " 0x3801" does not match my Yoga9 14IAP7 ! My subsystem is [17aa:381c], and my codec is [17aa,3863] See the alsa-info links for verification. So I find that including the modprobe option: >> options snd_sof_intel_hda_generic hda_model=17aa:3801 results in: >> $ cat /sys/module/snd_sof_intel_hda_generic/parameters/hda_model >> 17aa:3801 And then sound works as expected (6.11.4 kernel). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958019 Title: [Lenovo Legion7 16ACHg6 82N6, Realtek ALC287, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/sound-2.6/+bug/1958019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
